CYLINDRICAL BRUSH.

SPECIFICATION forming part of Letters Patent No. 397,076, dated January 29, 1889.

Application filed September 23, 1886. Serial No. 214,352. (No model.)

To a "whom it may concern.-

Be it known that I, GEORGE ,GLADDING, a citizen of the United States, and a resident of Chester, county of Middlesex, State of Connecticut, have invented new and useful Improvements in ylindrical Brushes, of which the following is a full and exact description, reference being had to the accompanying drawings, making part of this specification.

This invention relates to improvements in cylindrical brushes; and it consists in the construction and arrangement of the parts whereby the bristles are bound firmly in the handle. The bristles are inclined gradually from an upright to a horizontal position, to form an even cone, and loosening and slipping of the fastening are prevented.

In the drawings, Figure 1 is a side view of the grooved handle used in the manufacture of brushes of this nature. Fig. 2 is a view of the handle with the bristles arranged for forming the improved in ft and attached to the handle. Fl 5) is a view of the handle and the improved tui't complete. Fig. 4 is a view of the completed brush.

The letter A designates the handle of the brush. Near one end the handle is provided with the parallel grooves I; and terminates in the knob The grooves B are gradually undercut near the end to throw the bristles toward the knob (I. The knob G is formed with the smaller end or neck toward the grooved portion of the handle, substantially as shown. At the base of the neck of the knob (L a small hole is sunk in the handle for the reception of the end of the wrapping-wire. The wrapping-wire is inserted in the hole at the base of the knob (l and bent upward. The bristles are then laid across the grooves in the handle with their middle passing over the depression formed at the base of the neck of the knob ('3. The wrapping-wire is passed around these bristles once or twice, and the bristles are brought down tightly into the depression. The wire is again bent up to allow the bristles to pass. The half of the bristles above the wrapping are now caught and bent down over it. The wire is then passed over and around the bent portion of the bristles, bindin them firmly. The next line is formed by layingthe bristles over the next groove, as in forming the tuft. The wrapping-wire is then brought through a groove, D, cut in the intervening wood, and passed over and around the bristles, bringing them down into the slots, raising their ends, and throwing them forward toward the tuft by reason of the undercut portion of the slot. line being formed in the same way, and taking their slant from the incline ot' the slots. After the last line is formed a small hole is made through thehandle and the wire passed through it and clinched.

By passing the binding-wire through the grooves D and wrapping it down the displacement of the said wire is prevented and the bristles held firmly to the said handle, as shown.

\Vhat I claim is In a cylindrical brush such as described, the combination of a handle provided at the brush end with grooves passing around the said handle, said grooves being undercut, substantially as described, and small grooves connecting the said undercut grooves, bristles having their center-s drawn into the .said grooves, and a wrap1')ing-wire rigidly attached to the said handle and wrapped over the said bristles, drawing them into the said undercut grooves and fitting in the said small grooves connecting the said undercut grooves, substantially as set forth and described.

In testimony whereof I have hereunto set my hand this 16th day of September, A. D. 1886.

GEORGE GLADDING.
